A former FBI agent who was hired by the Department of Justice after participating in the 2021 insurrection says he has resigned from the federal agency due to his inability to “fully expose” government abuses from the inside.

Jared Lane Wise, who took a job as a counselor to Justice Department pardon attorney Ed Martin Jr. last July, said he handed in his resignation on Thursday.

“I returned to Washington to fully expose the abuses by the FBI and DOJ against J6 defendants, but it became clear that this will only happen from outside of government,” he posted on X. “So I left and will do so.”

Wise was charged with breaching the Capitol during the violence and repeatedly shouted “kill ’em” as he watched rioters assault officers outside the building, according to an FBI agent’s affidavit. He was one of nearly 1,600 participants who were ultimately pardoned by President Donald Trump last year.

A DOJ spokesperson confirmed his resignation to HuffPost on Friday, saying it had been “long planned.”
